Void value expression for 'retry'

ruby-talk
1

following code returns,
retry.rb:13: void value expression

What is wrong with this code?

#!/usr/bin/env ruby

retry_count = 0
retry_max = 4

begin
        sleep 30

rescue Interrupt
        if ( retry_count < retry_max)
                retry_count++
                retry
        end
rescue
        raise
end

Thanks,

retry_count++ is not valid ruby code. so that could be causing some
problems.

Ruby doesn't have the post-increment (++) operator. Use retry_count += 1 instead.
